I like the idea and design so far, but I read another comment in here that said nobody uses cards, and it made me realize I probably wouldn't use a card. But in Ingress, people do use badges, especially at Anomalies (giant events organized by Niantic where hundreds/thousands of people come together to battle at the same time in major cites, with different rules than normal, and to advance the storyline. Events like that will eventually happen with PoGo as well. Just watch the trailer.). So you could make something like that. A lot of them are like vertical cards worn on lanyards, but there's other types too. There's even a Badge Maker app to make your own (even if some of the presets aren't too cool), and each Anomaly has its own logo, so it usually comes with a new design (and local communities make unique designs for their own major cities). You could get some ideas from those for what info might be cool to add. If you want something permanent, some of these won't apply, but you could optionally add stuff like player level, main/favorite battling pokemon, country/county of play, personal logo or player image, qr code that links to local community website, etc.
